Look, if I owned and ran a business, and all the profits were mine to keep, I would slog 70 hours too, to build it up and get more money.
From that POV, NRN statement makes sense but that is it.
But as an employee, I get paid for my time, and india isn't really good about OT. We are exploited enough anyway.
Recently so many heart attacks are happening, we dont get physical activity because we slog at work and then dont get time.
In any case we should have better work life balance, and re-approach what "work" even is.
Life is so unpredictable, I would rather work 4 days and spend time with family and loved ones than slog for a billion dollar company making mindless profits by layoffs and unethical practices like keeping wages low.
Also, work done should not be measured in number of hours of work, that is IT coolie mindset of NRN which shows.
